(His)6 -tag recombinant hemoglobin I from Lucina Pectinata: A novel hydrogen sulfide protein donor
(2020-07)
Hydrogen Sulfide (H2S) is a gasotransmitter involved in physiological and pathological
processes in humans and animals. It is produced endogenously in humans through enzymatic
pathways. H2S is associated with the ...
Vibration-based stiffness and damping matrices updating of a sandwich composite bean
(2004-05)
This investigation seeks to develop a dynamic model capable of predicting the
dynamic behavior of a sandwich composite beam. This work is based on the previous
works of Lancaster, Pilkey and Ortiz. A vibration-based ...
Workplace spirituality: a comparative study
(2010)
The purpose of this investigation was to have a better understanding on governmental employees’ attitudes and perceptions towards spirituality in the workplace. The sample for this research was obtained from various ...
Model for the bouncing process of an air bubble interacting with an inclined wall
(2011)
A model to predict the bouncing of an air bubble rising through an unbounded quiescent liquid and impinging on an inclined wall has been derived. This model is an extension to three dimensions of previous models in one and ...
Geology and structure of the north Boquerón Bay- Punta Montalva Fault System
(2010)
The North Boquerón Bay-Punta Montalva Fault Zone is an active fault system that cuts across the Lajas Valley in southwestern Puerto Rico. The fault zone has been recognized and mapped based upon detailed analysis of ...
Reconstructing sea surface temperatures in the Caribbean during the early-mid Holocene from a reef exposure in Cañada Honda, Enriquillo Valley, Dominican Republic
(2015)
Temperatures during the Holocene are driven by seasonal changes in insolation; however, a better understanding of insolation mechanisms and how it affects tropical climate is still necessary. This study presents annual ...
A new multidimensional crystallographic fast fourier transform
(2004)
The Fast Fourier Transform (FFT) describes a well known set of algorithms that allows a fast evaluation of the Discrete Fourier Transform (DFT). In FFTs, the original sequence is replaced by the sum of a shorter sequence ...
Optimization-driven meta-analysis: The simultaneous search for cancer biomarkers with multiple microarray experiments
(2014)
In bioinformatics, it is possible to generate experimental data at a high pace. For example, microarrays can provide large amounts of data for genetic relative expression in illnesses of interest such as cancer. These data ...
Motivational language strategies in a basic english classroom in Puerto Rico
(2018)
English language teaching has long been the source of education policy debates in Puerto
Rico. Efforts have been made to increase bilingualism in students; however, textbooks used to
teach English have had little ...
Dsd variations on rain-rate estimate algorithms of x- band polarimetric radar and rainfall characterization in tropical environments using 2dvd, rain gauges and trmm data
(2005)
Data from NASA TRMM satellite and rain gauges, the rain rate per hour was studied. The comparison took place in San Juan, Puerto Rico; when the Tropical Storm Jeanne passed over the island of Puerto Rico. Natural variations ...
